About a decade ago, TIME Magazine published A World Without Bees [1]

Since then, many people seem to think bees are on the edge of extinction.

In fact, there are more bees now than ever before [2]

> Participants were instructed in their respective native languages to estimate roughly how much time it took

If they really want to claim that the “language you speak” changes your perception of time, then they should have avoided the confounding variable of translation discrepancies in experiment instruction.

For example, design some simple UI which does not need to be explained.

Profound or contrapositive [1]?

P = reader

Q = not steal

not P = does not read

not Q = Theif

P - > Q

not Q - > not P

Culture-dependent? I recall the story from France of the second-grader who, asked what 2x3 equals, replied "3x2", knowing only that multiplication was commutative.

This is a classic joke making fun of the issues with French education based on the Bourbaki [1] school of mathematics, see [2] for more discussion. Different issues than the USA, but also bad in my opinion.

Maybe too late to give you any helpful advice, but setting up Advanced Protection may make sense. You need to buy at least two (preferably three) YubiKeys and the password plus any of these keys allow you to login to your account. Nothing more, nothing less. Costs a few bucks, but at least the auth flow is very clear.

Another thing you can do is to wait for a week and see if anything changes. Having the session last for more than a week may give you more options in passing the challenge.

Agree that RPN is great, though it looks like RPN isn't available in CAS mode.
dfdz · 3 years ago
I did not realize RPN is not available for CAS, that is disappointing.

Is an HP 50G really the last of its kind? Hard to suggest since it’s priced like a collectors item now…

HP Prime on Reverse Polish Notation (RPN) mode [1, Page 47]. RPN is a basic stack based programming language, which is really fun to use [2].
